Materials Data on Ca4Sn3S10 by Materials Project
Abstract
Ca4Sn3S10 crystallizes in the orthorhombic Pbca space group. The structure is three-dimensional. there are two inequivalent Ca2+ sites. In the first Ca2+ site, Ca2+ is bonded in a 7-coordinate geometry to eight S2- atoms. There are a spread of Ca–S bond distances ranging from 2.81–3.52 Å. In the second Ca2+ site, Ca2+ is bonded to six S2- atoms to form distorted CaS6 octahedra that share corners with two equivalent SnS6 octahedra, corners with eight equivalent CaS6 octahedra, edges with two equivalent SnS6 octahedra, and a faceface with one SnS6 octahedra. The corner-sharing octahedra tilt angles range from 43–72°. There are a spread of Ca–S bond distances ranging from 2.78–2.99 Å. There are two inequivalent Sn4+ sites. In the first Sn4+ site, Sn4+ is bonded to six S2- atoms to form corner-sharing SnS6 octahedra. The corner-sharing octahedra tilt angles range from 38–44°. There are a spread of Sn–S bond distances ranging from 2.58–2.62 Å. In the second Sn4+ site, Sn4+ is bonded to six S2- atoms to form SnS6 octahedra that share corners with two equivalent CaS6 octahedra, corners with five SnS6 octahedra, edges with two equivalent CaS6 octahedra, and a faceface with one CaS6 octahedra.
